Hi,
I found that this sql will throw error: Invalid path: 'io.github.zhengyhn.practice.hibernate.ABStatus.A'.
{code:java}
select s from Sample s where s.upperStatus = io.github.zhengyhn.practice.hibernate.ABStatus.A
{code}
But the below sql works.
{code:java}
select s from Sample s where s.lowerStatus = io.github.zhengyhn.practice.hibernate.BaStatus.A
{code}
I read the code and found this is because of these lines of code in org.hibernate.internal.util.ReflectHelper.
{code:java}
if ( conventionalJavaConstants &&
!JAVA_CONSTANT_PATTERN.matcher( name ).find() ) {
return null;
}
{code}
And the JAVA_CONSTANT_PATTERN is as below.
{code:java}
private static final Pattern JAVA_CONSTANT_PATTERN = Pattern.compile(
"[a-z\\d]+\\.([A-Z]{1}[a-z\\d]+)+\\$?([A-Z]{1}[a-z\\d]+)*\\.[A-Z_\\$]+", Pattern.UNICODE_CHARACTER_CLASS);
{code}
This pattern indicate that the constant name must begin with an upper case alphabet. So "ABStatus" cannot be recognized as valid constant name.
However, in my real-world project, we use GSStatus as the enum class name. I have to change it to GsStatus currently.
I suggest changing this pattern to
\{code:java}
" \ [a-z\\ \\ d]
+ \\ .( \ [A-Z]+ \ [a-z\\ \\ d]+)+\\ \\ $?( \ [A-Z] \ {1} \ [a-z\\ \\ d]+)*\\ \\ . \ [A-Z_ \\ +
+ $]+".
\{code}
I have written a simple project for finding this issue. You can refer it as reference. [ https://github.com/zhengyhn/java-practice/tree/master/hibernate-enum |https://github.com/zhengyhn/java-practice/tree/master/hibernate-enum] |
